I have a 581i the old version without vents and standard(substandard plastic) remote. The software was updated by wadia by changing the control processor board. After software update the CD/SACD layer selection works with MODE switch on remote. One has to press it ONLY ONCE taking good aim at the unit, else you may end up where you started.
The transport control logic still don't show up the time of the disc if stopped mid way of a disc and the player fails to boot up properly with a CD loaded in the tray. My player takes clear 10 seconds to load a CD, SACD is bit faster and hybrid takes 2-3 secs more.
Eve with all this quirkiness I like the player because for that money I could not find a better one for my kind of taste.
